Asked about De Niro-Rodriguez's death, a spokesperson for the New York City Police Department told CBS News that officers responded to a 911 call on Sunday afternoon and subsequently found a man who was unconscious and unresponsive inside a building in lower Manhattan.

Fentanyl is a synthetic opioid, akin to morphine but more potent, which is sometimes abused on its own or found laced in other drugs. Health officials, including those at the U.S. Centers for Disease Control and Prevention, have warned in recent years that its prevalence is on the rise, as is its role in overdose deaths nationwide.
